Fix from Sun for related overrideredirect issue is in OpenJDK6 and OpenJDK7. The Metacity issue has been marked as not a bug in the JDK, but one in Metacity: see S6514512. Metacity has left bug open for a few years now, but is not hurrying to fix it (current metacity behavior does meet spec, even if it is not what most would expect) so for the forseeable future it must remain in IcedTea.

Amalgamation of cc-interp-backedge (Remove some duplicated code in DO_BACKEDGE_CHECKS), cc-interp-jvmti (Disable some JVMTI capabilities which are unsupported or do not work with the C++ interpreter), ia64-bugfix (Remove workaround for IA64 GCC bug), s390-serialize (Correctly detect serialization segfaults on s390) and test-atomic-operations (Add check to see if GCC's sync_lock_test works).
